Geological and geophysical investigations of an Apollo 9 photo anomaly near Point of Pines, Arizona
Calvin S. Bromfield, G. P. Eaton, D. L. Peterson, J.C. Ratte
1972, Open-File Report 72-51
An infrared photograph of southeastern Arizona, taken during the Apollo 9 multispectral terrain photography experiment in 1969, reveals a ringlike feature, some 3-4 miles (5-6 kin) in diameter, on the Natanes Plateau, 35 miles (56 kin) north of the town of Safford. Because the feature occurs in an area of...
Oil-shale assays on Grand Mesa, west-central Colorado
John R. Donnell
1972, Open-File Report 72-93
The attached diagram shows the Fischer assay histograms of oil shale from 4 core holes drilled on Grand Mesa. Core-hole locations are shown on-an insert map of Grand Mesa in the lower right corner of the diagram....
Regional and other general factors bearing on evaluation of earthquake and other geologic hazards to coastal communities of southeastern Alaska
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-230
The great Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in seismically active regions. As a result, nine communities in southeastern Alaska were selected for reconnaissance investigations as an integral part of an overall program to evaluate earthquake and other geologic hazards...
Reconnaissance engineering geology of the Haines area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-229
The Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in urban areas. Study of the Haines area constitutes an integral part of an overall program to evaluate earthquake and other geologic hazards in most of the larger Alaska coastal communities. The evaluations...
Evaluation of yields of wells in consolidated rocks, Virginia to Maine
Dagfin John Cederstrom
1972, Water Supply Paper 2021
In the North Atlantic region, Virginia to Maine, yields of industrial and municipal wells are the most reliable indicators of the water-yielding potential of consolidated rocks. Generally, such wells represent efforts to develop a maximum supply of water, they are 350 to 500 feet deep, and they utilize 60 to...
The status of mineral resource information on the major land withdrawals of the Alaska Native Claims Settlement Act of 1971
Alaskan Geology Branch
1972, Open-File Report 72-394
This report is an analysis of the adequacy of the present level of geologic knowledge for making mineral resource potential evaluations of 126 federal land withdrawals made under the Alaska Native Claims Settlement Act. The withdrawals considered are Native village and regional deficiency areas (Sec. 11.A.3, ANCSA), classification and national...
Placer deposits of Alaska
Edward Huntington Cobb
1972, Open-File Report 72-71
Placer deposits, in addition to their intrinsic value, serve as indicators of areas of potential development of lode deposits. Any possibility that Alaska may again become an important source of metallic mineral commodities depends in part on an inventory of placer deposits and a knowledge of the geology of their...
Water resources data for Kansas, water year 1971; Part 2, Water quality records
Water Resources Division, U.S. Geological Survey
1972, Water Data Report KS-71-2
Water-resources data for the 1971 water year for Kansas include records of data for the chemical and physical characteristics of surface and ground water. Data on the quality of surface water (chemical, microbiological, temperature, and sediment) were collected from designated sampling sites at predetermined intervals such as once daily, weekly,...
Water resources data for Indiana, water year 1971
Water Resources Division, U.S. Geological Survey
1972, Water Data Report IN-71-1
Water resources data for the 1971 water year for Indiana, including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, and records of water-quality data on the chemical and physical characteristics of surface water are given in this report. Records for a few pertinent gaging...
Geology and water resources of the Bitterroot Valley, southwestern Montana, with a section on chemical quality of water
R. G. McMurtrey, Richard L. Konizeski, M. V. Johnson, John H. Bartells, H. A. Swenson
1972, Water Supply Paper 1889
The Bitterroot Valley is a Late Cretaceous structural basin that was partly filled at its deepest point by more than 1,640 feet of Tertiary sediments. These sediments grade valleyward from coarse colluvial deposits along the edges of the valley to fine-grained deposits and then to coarse channel deposits of the...
